CEFUROXIME AND DEXTROSE IN DUPLEX CONTAINER vs CEPHALOTHIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefuroxime is a second-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), leading to cell lysis and death.
Cephalothin is a first-generation cephalosporin that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby blocking peptidoglycan cross-linking. It has activity against gram-positive cocci (e.g., Staphylococcus aureus, Streptococcus pyogenes) and some gram-negative bacilli (e.g., Escherichia coli, Klebsiella pneumoniae).
750 mg to 1.5 g intravenously every 8 hours; for severe infections, up to 1.5 g every 6 hours.
1-2 g IV every 4-6 hours; maximum 12 g/day.

Terminal elimination half-life: 1.2-1.6 hours (prolonged to 15-22 hours in severe renal impairment, CrCl <10 mL/min); requires dose adjustment in renal failure
0.5-1 hour in patients with normal renal function; prolonged to 2-8 hours in moderate renal impairment (CrCl 30-50 mL/min); up to 20-30 hours in end-stage renal disease; due to rapid elimination, frequent dosing (q4-6h) is required for continuous bactericidal levels.
Renal: 80-90% unchanged via glomerular filtration and tubular secretion; fecal: <1%
Primarily renal (60-90% unchanged) via tubular secretion and glomerular filtration; minor biliary excretion (less than 5%); hepatic metabolism to desacetylcephalothin (active but less potent) accounts for about 20-30% of dose; fecal elimination negligible.
